To all 'whom 'it may concern:

Beit lrnown that l, Mannion BOUCHET, a citizenof the French Republic, and a resiend of the body is provided with a recess 1n which 1s arranged a lamp 0,' an asbestos bastion chamber al and a liuc o2.

Underneath the recessA where is ,have invented a Portable Vulcanizing -Applaced thelamp is arranged an air inlet el paratus, of which the following is a. full, which may be closed by a screen e prbvided clear, and exact description. with small holes e2. This screen is carried The invention relates to a portable vulby arms j" frictionally rotating on milled 10 canizing apparatustor heating' at constant heads g1 mounted on the aXis g.

The screen c is removed from the 'apparatus by means of which the bodies to opening el, by turning the arms f on the be treated are brought automatically to the milled heads g1, the latter being maintained required temperature and the heating is out immovable, since the blades L are held in the oil" automatically when the time 'for heating solidilied alloy.

Fig. 2 is4 a corresponding` 'plan ing operatie view thereof. liig. 3 is asie.V View. Fig. d AS it will be seen, the Working of the is a section made according to line A-A of apparatus comprises two periods. In the Fig, 3. Figs. 5 and 6 show the application first period, an intensive heating is pro- 105 of the apparatus. Figs. 7 and 8 show a duced, adapted to bring the apparatus to modification. the ynlcanif/.ing temperature. ln the second As shown in the drawings, the apparatus period, the apparatus is maintained at a is constituted by av body a the lower face of constant temperature, during the time neces. which is slightly curved. This body is insary for themlcanization. The cutting olf ternally recessed, so as' to presentr comof the intensive heating, on the one hand ll 1e rear the other hand, are produced automatically at the desired time Without the apparatus requiring anyl attent-ion.

The arrangement of the apparatus and of' the fastening bonds reduces to theminimumV the loss of heat by eonductibility. The arrangement of the stand s permits the indiarubber pieces to be repaired without the same being mounted on the Wheel, according to their normal incurvation and not flatwise; which is preferable.

Figs. 7 and 8 show a modification of the releasing device for the screen, in which the screen @carries an armature b attracted by the magnet d. The'armature is made of an alloy, of steel or nickel for example,- which ceases to be attracted by the magnet at a certain temperature depending on the amount of nicleh- Therefore the alloy may be suitably chosen so that the armature is released at the temperature for vulcanization and lowers, at this moment, the heat emitted by the lamp, as in the preceding arrangement.

Claims: l

l An automatic portable vulcanizing apparatus comprising a hollow block, a lamp,

an air supply opening, a screen which may ,close said opening and provided with small holes7 an automatic releasing device for the screen and blades integral With the axis of the screen and plunging in a bath of fusible alloy. a

3. An automatic portable vulcanizing apparatus comprising a hollow block having a hollowedand incurred face presenting in concave form the shape of the indiarubber tires, a lamp, an air supply opening, a screen which may close said opening and provided with small holes and an automatic releasing system for the screen.
